FRANCESCO STUPPILLO, OF WATERTOWN, NEW YORK.

GAGE.

Specification of Letters Patent.

Application filed May 20, 1916, Serial No. 98,710.

To all whom t may concern.'

Be it known that I, FRANCESCO STUPPILLO, a subject'of the King of Italy, residing at Vatertown, in the county of JeHerson and State of New York, have invented certain new and useful Improvements in Gages, of-

whereby a single means lserves both to maintain an indicator-carrying slide on the gage-bar'and the indicator on the slide reliably in adjusted positions.

l/Vhen read in connection with the description herein, the details of construction and arrangement of parts contemplated by the invention will be apparent from the accompanying drawing, forming part herecf, wherein an embodiment of the invention is disclosed, for purposes of illustration.

While the disclosures herein exemplify a preferable form of the invention, it is to be understood. that it is not the intention to be limited necessarily thereto in interpretation of the claims, as changes can be made within the limits of the claims without departing from the nature and spirit of the invention.

Like reference-charactersl refer to correspending parts in the views of the drawing, of which- Figure 1 is a perspective view of the gage;

Fig. 2 is a perspective view of the slide and indicator-bar;

Fig. 3 is a view of the slide and indicatorbar in place on the gage-bar, the latter being shown in cross-section;

Fig. 4 is a perspective view of the gagebar; and

Fig. 5 is a view illustrative of the use of the gage at bends of a pipe, tube, or bar.

Having more particular reference to the drawing, 6 designates a gage-bar, which is a straight length of metal, wood, or other suitable material, but preferably metal and rectangular in cross-section. A saddle or seat 7 is secured near each end of the bar or made integral therewith, and each of the saddles or seats is concave, as shown at 8, so that it is adapted to contact with, and in a measure to conform to, the curved surface of a tube or bar without being readily displaced therefrom while the gage is in use.v From the face on the same side as the saddles or seats the bar is formed with a slot 9 opening therethrough to the opposite face and extending for'a part of the length of the bar. A slot 10 extends from one of the other faces of the bar to and opens into the slot 9 at a place about midway of the thickness of the bar. The slots 9 and 10 are disposed substantially at right angles to each other. The bar has a graduated scale l10n the face to which the slot 10 opens and a similar scale 12 on the opposite face. v

A slide 13, of a shape corresponding to the cross-section of the gage-bar 6 and in the form of a sleeve envelops and is slidable on the gage-bar. A graduated indicator-bar 14 extends through the sleeve and is accommodated by the slot 9 of the gagebar. A screw 15 is carried by the slide substantially at right angles to the indicator-bar, and it extends into slot 10 so that its inner end is capable of engaging the indicator-bar.

When it is desired-to move the slide to a particular position on the gage-bar, to move the indicator-bar to cause its contact end to extend more or less beyond the plane of the contact surfaces of the saddles or seats 7, or to adjust both the slide and indicator bar, the screw 15 is turned to relieve its end from pressure against the indicator-bar thereupon the parts are moved'to the adjustment desired, and then the screw is turned to lcause its inner end to press against the indicator-bar. This action of the screw operates to clamp and hold the indicatorbar against the wall of the slot 9 opposite to the end of the screw and thus maintain the indicator-bar in position, and it also serves to pull the opposite side of the sleeve against the corresponding face of the gage- `bar and thereby maintain the sleeve against movement longitudinally of the bar.

It will be seen that by this arrangement one screw operates eiiiciently and reliably to maintain both parts against displacement and that the necessity of employing a separate screw for each of the adjustable parts ,is obviated.

Preferably the indicator-bar has a fairly Patented Feb. 20, 1917.

moved when the screw is loosened` therethrough, so that it will not fall out when the screw 1s loosened and so that it requires pressure of a thumb or finger or a tap of the hammer or the like to move it longitudinally; and the slide ts the gagebar fairly tightly so that it is not too easily Thus either the slide or the indicator-bar, when the screw is loosened, may be moved to i a new adjustment without necessarily disturbing the adjustment of the other. Home ever, while it is preferable that the parts iit as just described, that is not absolutely necessary, as they normally are held securely against displacement by the screw when tightened; and, when an adjustment is to be made, the screw may be turned only sufficiently to permit movement oi' the parts without entirely loosening them.

sitter the parts are brought to the adjusty ed positions required tor the use to which the is to be put, the device then is ready to measi'n'e or gage at the position of the iiulicator-bar the defiection 'from the plane of the Contact surfaces oi? the saddles or seats, or the relative position of a surface or point with respect to that plane. Thus, as illustrated by Fig. 5, the device is adapt ed to gage the bends or angles of a pipe, tube, or bar, so that a plurality of them can be made with practically identical bends or angles. The device is placed with its saddles or seats against the article vto be measured so that it will straddle or span the bend, and thus the indicator-bar shows whether the bend is correct.

Having thus described my invention, what l claim as new, and desire to secure by Letters. Patent, is- Y l. A gage comprising a bar formed with a slot extending therethrough from one face to the opposite face and with another slot `opening into the first mentioned slot and to another face of the bar, Va slide movable longitudinally on said bar, an adjustable indicator-bar carried by said slide and extending through said :51st-mentioned slot, and a screw carried by said slide and extending into said second-mentioned slot and arranged to engage said indicator-bar and to hold boththat bar and said slide in adjusted positions.

2. A gage comprising a bar formed with a slot extending therethrough from one 'face to the opposite face and with another slot opening into the first-mentioned slot and to another face ot the bar, a' coiltact-seat at each end of said bar, a slide movable longitudinally on said bar, an adjustable indicator-bar carried by said slide and extendingr through said tirst-mei'itioued slot, and :i screw carried by said slide and extending.; into said second-mentioned slot and arranged to engage said-indicator-bar and to hold both that bar and said slide in adjusted positions.
